Image forming device

A method of reducing static electricity, comprising:

• forming an image on a printing medium;
• sandwiching the printing medium between a first roller and a second roller, the first roller positioned on a downstream side from image forming in a conveyance path and the second roller positioned on the downstream side from image forming in the conveyance path and faces the first roller;
• conveying the printing medium in a first direction;
• reducing static electricity of the printing medium using a static elimination brush;
• moving the static elimination brush between a first position that does not intersect a first conveyance path on a downstream side in the conveyance path and a second position that intersects the first conveyance path;
• and
• controlling the moving during the conveyance of the printing medium;
• positioning the static elimination brush at a position different from the second position until a front end of the printing medium passes an intersection position at which the static elimination brush and the first conveyance path intersect if the static elimination brush is positioned at the second position;
• and
• moving the static elimination brush to the second position after the front end of the printing medium passes the intersection position until a rear end of the printing medium passes the intersection position.

A static electricity reducing system, comprising:

• a static elimination brush configured to eliminate static electricity of a printing medium;
• a moving component configured to move the static elimination brush between a first position that does not intersect a first conveyance path on a downstream side of a roller unit in the conveyance path and a second position that intersects the first conveyance path;
• and
• a controller configured to control the moving component during the conveyance of the printing medium, position the static elimination brush at a position different from the second position until a front end of the printing medium passes an intersection position at which the static elimination brush and the first conveyance path intersect if the static elimination brush is positioned at the second position, and move the static elimination brush to the second position after the front end of the printing medium passes the intersection position until a rear end of the printing medium passes the intersection position.
